Red Hat Update Agent
The
Red Hat Update Agent
is your connection to Red Hat Network. It enables you to register your
systems, create System Profiles, and alter the settings by which your organization and RHN interact.
Once registered, your systems can use the
Red Hat Update Agent
to retrieve the latest software
packages from Red Hat. This tool allows you to always have the most up-to-date Red Hat Enterprise
Linux systems with all security updates, bug fixes, and software package enhancements.
Remember, this tool must be run on the system you wish to update. You cannot use the
Red Hat
Update Agent
on the system if it is not entitled to an RHN service offering.
Warning
Only systems running Red Hat Enterprise Linux 3 and later can use the
Red Hat
Update Agent
to register with RHN. Systems running Red Hat Enterprise Linux 2.1
must use
Red Hat Network Registration Client
before starting the
Red Hat Update
Agent
. Refer to
